↳ | dalvik.system.VMRuntime |
This class is deprecated.
this is an internal Dalvik class that is not appropriate for
general use. It will be removed from the public API in a future release.
Provides an interface to VM-global, Dalvik-specific features. An application cannot create its own Runtime instance, and must obtain one from the getRuntime method.

From class java.lang.Object

Requests that the virtual machine collect available memory, and collects any SoftReferences that are not strongly-reachable.
Returns the number of externally-allocated bytes being tracked by trackExternalAllocation/Free().
Returns the minimum heap size, or zero if no minimum is in effect.
Returns the object that represents the VM instance's Dalvik-specific runtime environment.
Gets the current ideal heap utilization, represented as a number between zero and one. After a GC happens, the Dalvik heap may be resized so that (size of live objects) / (size of heap) is equal to this number.
Does not return until any pending finalizers have been called. This may or may not happen in the context of the calling thread. No exceptions will escape.
Sets the desired minimum heap size, and returns the old minimum size. If size is larger than the maximum size, the maximum size will be used. If size is zero or negative, the minimum size constraint will be removed.
Synchronized to make the order of the exchange reliable.
This is only a hint to the garbage collector and may be ignored.
size | the new suggested minimum heap size, in bytes |

Sets the current ideal heap utilization, represented as a number between zero and one. After a GC happens, the Dalvik heap may be resized so that (size of live objects) / (size of heap) is equal to this number.
This is only a hint to the garbage collector and may be ignored.
newTarget | the new suggested ideal heap utilization. This value may be adjusted internally. |

IllegalArgumentException | if newTarget is <= 0.0 or >= 1.0 |
